Question

Which best describes the wavelength of a simple wave?

A.The distance from the crest of a wave to the crest of the
next wave
B.The distance from the crest of a wave to the trough of the
next wave
C.The number of waves that pass a certain point in a minute
D.The speed at which the wave travels in m/s

Answer 1

I think it is A

Explanation: Wavelength is the distance from one crest to another, or from one trough to another, of a wave (which may be an electromagnetic wave, a sound wave, or any other wave). Crest is the highest point of the wave whereas the trough is the lowest.
